FIG. 2 is an enlarged view of a region ‘Z’ of FIG. 1. FIG. 3 illustrates an outer surface of a holder in a region ‘Z’ of FIG. 1.

Referring to FIGS. 1, 2, and 3, the hole H may penetrate the holder 140 from the inner surface 140 a of the holder 140 to the outer surface 140 b of the holder 140. The hole H may be provided in a sidewall part or a top part of the holder 140. The hole H may have, for example, a cone-shaped inner space. For example, a cross-section of the hole H may have a trapezoid-shape. The hole H may have, for example, a circular shape or an elliptical shape when viewed in a direction from the outer surface 140 b to the inner surface 140 a. A diameter D1 of an inner end of the hole H provided in the inner surface 140 a of the holder 140 may be, for example, less than a diameter D2 of an outer end of the hole H provided in the outer surface 140 b of the holder 140.

The first surface 141 a may face the inner surface 140 a of the holder 140, and the second surface 141 b may face the outer surface 140 b of the holder 140. The first stopper 141 may have, for example, a shape corresponding to the inner space of the hole H. For example, the first stopper 141 may have a cone-shape corresponding to the cone-shaped inner space of the hole H. In an embodiment, the first stopper 141 may have a cross section of, for example, a trapezoid-shape. Each of the first and second surfaces 141 a and 141 b of the first stopper 141 may have, for example, a circular shape or an elliptical shape.

FIG. 4 is a cross-sectional view illustrating a semiconductor package according to an embodiment of the inventive concept. In the present embodiment, the descriptions of the same elements as described above will be omitted or mentioned briefly for the purpose of ease and convenience in explanation.

Referring to FIG. 4, a semiconductor package 2 may be, for example, a surface mounting package including a package substrate 200 and an image sensor device 101 mounted on the package substrate 200. The image sensor device 101 may include, for example, a substrate 110, an image sensor chip 120, bonding wires 130, a holder 140, and a transparent cover 150. Bumps 160 may electrically connect the image sensor device 101 to the package substrate 200.

The holder 140 may have at least one hole H. The hole H may be formed in a sidewall part or a top part of the holder 140.

The adhesive stopper 142 may include, for example, an adhesive material (e.g., an epoxy-based material or a polyimide-based material).

[Method of Manufacturing Semiconductor Package]

FIGS. 5 and 6 are cross-sectional views illustrating a method of manufacturing a semiconductor package according to an embodiment of the inventive concept. In the present manufacturing method, the same descriptions as described above will be omitted or mentioned briefly for the purpose of ease and convenience in explanation.

Referring to FIG. 5, the image sensor device 100 described with reference to FIG. 1 may be provided. For example, the image sensor chip 120 may be bonded to the substrate 110 through the adhesive layer 121 and then the holder 140 may be fixed on the substrate 110. Subsequently, the transparent cover 150 may be combined with the holder 140. The holder 140 may have, for example, a hole H. The hole H penetrates the holder 140. The holder 140 may include the first stopper 141 and the second stopper 143. The first stopper 141 may be disposed in the hole H and the second stopper 143 may be disposed on the outer surface 140 b of the holder 140. A housing process of combining the transparent cover 150 with the holder 140 may include, for example, applying an adhesive to the transparent cover 150 or the holder 140, and hardening the adhesive. Pressure in the space C of the image sensor device 100 may be increased in the process of hardening the adhesive by, for example, ultraviolet rays or heat. The hole H and the vent-hole VH may exhaust the high pressured air to the outside of the image sensor device 100. Bump parts 161 may be formed on the outer pads 117. The bump parts 161 may be formed before or after the combination of the holder 140 and the transparent cover 150.

Referring to FIG. 6, the image sensor device 100 may be mounted on the package substrate 200 through, for example, bumps 160. For example, in an embodiment, the image sensor device 100 may be located on the package substrate 200 such that the bump parts 161 of FIG. 5 face the package substrate 200. Thus, the bump parts 161 of FIG. 5 may become in contact with the first pads 213 of the package substrate 200. The bumps 160 may be formed by, for example, soldering the bump parts 161 of FIG. 5. In an embodiment, the bump parts 161 of FIG. 5 may include, for example, lead (Pb)-free solder. For example, the bump parts 161 of FIG. 5 may be soldered at a temperature in the range of about 180 degrees Celsius to about 300 degrees Celsius (e.g., about 245 degrees Celsius), thereby forming the bumps 160. If the soldering temperature is less than about 180 degrees Celsius, the bumps 160 may not be formed. The pressure of the space C may be increased during the mounting process using, for example, the soldering of the image sensor device 100. At this time, the hole H and the vent-hole VH may exhaust the high pressured air of the space C to the outside of the image sensor device 100. Thus, it is possible to prevent the image sensor device 100 from being damaged by the pressure in the mounting process.

FIGS. 7 to 10 are cross-sectional views illustrating an operating principle of a first stopper according to internal pressure of an image sensor device. FIGS. 7 and 8 illustrate the image sensor device 100 and the package substrate 200 during the mounting process of the image sensor device 100. FIGS. 9 and 10 illustrate the image sensor device 100 and the package substrate 200 after the mounting of the image sensor device 100 is finished. Hereinafter, the same descriptions as described above will be omitted or mentioned briefly for the purpose of ease and convenience in explanation.

Referring to FIGS. 7 and 8, the inner pressure of the image sensor device 100 may be increased during the mounting process of the image sensor device 100. The first stopper 141 may be moved toward the outer surface 140 b of the holder 140 such that the side surface 141 c of the first stopper 141 may be separated from the inner surface of the hole H. That is, the side surface 141 c of the first stopper 141 may be separated from the holder 140. Thus, the high pressured air in the space C may be exhausted through the hole H and the vent-hole VH to the outside of the image sensor device 100. The second stopper 143 may prevent the first stopper 141 from being outputted from the hole H.

Referring to FIGS. 9 and 10, if the mounting of the image sensor device 100 is finished, an inner temperature of the image sensor device 100 may be reduced. Thus, the inner pressure of the image sensor device 100 may be reduced. The first stopper 141 may be moved toward the inner surface 140 a of the holder 140 such that the side surface 141 c may become in contact with the inner surface of hole H. That is, the side surface 141 c may become in contact with the holder 140. Thus, the first stopper 141 may close the hole H to seal the image sensor device 100. The first stopper 141 may prevent an external material from being inputted into the image sensor device 100. As a result, the first stopper 141 may protect the image sensor chip 120. The operating principle of the first stopper 141 may be applied to the process of housing the image sensor device 100.

FIGS. 11 and 12 are cross-sectional views illustrating a method of manufacturing a semiconductor package according to an embodiment of the inventive concept. Hereinafter, the same descriptions as described above will be omitted or mentioned briefly for the purpose of ease and convenience in explanation.

Referring to FIG. 11, the image sensor device 101 described with reference to FIG. 4 may be provided. The image sensor device 101 may include the hole H penetrating the holder 140. A high pressured air in the image sensor device 101 may be exhausted through the hole H during the housing process of the transparent cover 150 and the holder 140.

The bumps 160 may be formed to mount the image sensor device 101 on the package substrate 200. The bumps 160 may be formed by, for example, a soldering process. The soldering process may be performed at a temperature in the range of, for example, about 180 degrees Celsius to about 300 degrees Celsius (e.g., about 245 degrees Celsius). At this time, a high pressured air in the image sensor device 101 may be exhausted through the hole H. As a result, the hole H may control an inner pressure of the image sensor device 101 to prevent the image sensor device 101 from being damaged.

Referring to FIG. 12, if the mounting of image sensor device 101 is finished, an inner temperature of the image sensor device 101 may be reduced. Thus, the inner pressure of the image sensor device 101 may be reduced. An adhesive stopper 142 may be formed on the outer surface 140 b of the holder 140. For example, an adhesive may be applied to the outer surface 140 b of the holder 140 to close the hole H. Thus, the adhesive stopper 142 may be formed. The adhesive stopper 142 may prevent an external material from being inputted into the image sensor device 101. Thus, the semiconductor package 2 illustrated in FIG. 4 may be manufactured.
